I completely understand the emotions you have expressed here. In your dreams, everything is perfect. Your dreams can't disappoint you. Real relationships are scary, because that person can break your heart. It always involves taking a chance, taking a risk.
Your poem reminds me of a scene from one of my favorite TV shows of all time called My So Called Life. She tells her friend that maybe she likes the fantasy of her crush more than even him in real life.
Anyway, good poem. Honest and real.

I really like this. It describes how most teenagers are likely to feel: too afraid to let the dream become a reality. I am definitely going to read some of your other poems as they seem interesting. :)
